To all whom t may concern Be it known that we, Ismon Z. GARFIELD, acitizen of the United States of America, residing in New York, boroughof Manhattan, county and State of New York, and NATHAN GoLDrAR, acitizen of the United States of America, residing in New York, boroughof Brooklyn, county of Kings, and State of New York, have inventedcertain new and useful Improvements in Machines for Packaging Powders,of which the following is a specification. y

This invention relates to an improved machine for packaging powders,such as Seidlitz powders, Rochelle salts and similar powders formedicinal use, by which the powder is fed in accurately-measuredquantities and in a temporarily compressed state to an intermittently-moving paper-band from which wrapper-blanks of the required size arecut, elo-sed by a double-fold atfthe sides and ends and thensuccessively fed after the closed packages are subjected to pressure forcrushing the cakes in the same to a delivery and counting mechanismwhereby the manual work heretofore required for packaging such powdersis dispensed with, and the same quickly and effectively packaged withoutloss of powder; and for this purpose the invention consists of anorganized machine for packaging powders, which comprises means formeasuring uniform quantities of the powder, compressing them into cakesand delivering them to a. continuous intermittently-movable paper-bandbelow said compressing means. a folding mechanism for folding the sidesof the wrappers into a double-fold over the cakes, means for cutting offthe wrapperblanks from the continuous paper-band, and means for foldingthe ends of each wrapper on the body-portions of the same, and means fordelivering and counting said packages.

The invention consists further of certain details of construction of thedifferent cooperating parts of the machine, which will be first fullydescribed and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a plan-view of theleft-hand portion of our improved machine for packaging powders, Fig. 2is a vertical longitudinal section on line Llf--LL Fig. 1, Fig. 3 is aplan-view of the right-hand portion of the machine, Figs. 4, 4:, 4b and4 are vertical transverse sections showing the successive steps ofside-folding the wrapping-paper over the cakes of powder fed to thecontinuous, intermittently-moving band, Figs. 5 and 6 show respectively,a side-elevation and a vertical transverse section, on line 6-6, Fig. 3,of the powder-measuring, cornpressing and delivering mechanism, Fig. 7is a detail side-elevation of the lower portion of the feed-hoppershowing the means for regulating the supply of powder to the compressingmechanism, Fig. 8 is a sideelevation of the left-hand end of themachine, showing tently-feeding the paper-band, the cutting offmechanism, and the mechanism for folding and closing the ends of thewrappers, Fig. 9 represents a vertical, transverse section with themechanism for folding the ends of the wrappers over the bodypor tions ofthe same, and Figs. 10, 10b and 10 represent respectively perspectiveviews and an end-view of the wrappers in the different stages of foldingover and closing the ends of the same.

Our organized machine for packaging medicinal powders by mechanicalmeans into paper-wrappers consists of a machine for measuring thepowders in uniform quantities and temporarily compressing them intocakes, and feeding them to a continuous paper-band which isintermittently moved forward below ing mechanism, a primary folder forcreasing one side of the paper-band, a plurality of folders for doublingup and folding the sides of the paper-band, and intermittentlyactuatedcutting mechanism for cutting off the side-folded paper-band intoindividual wrappers, means for folding over and closin the ends of thewrappers, and means for de ivering the packaged powders successivelyinto a slidable tray for removing the same from the machine, and acounter for lthe mechanism for intermit-` the measuring and compress-Icounting the number of packages delivered suitable medicinal powder, butpreferably either sodium bi-carbonate or pulverized tartaric acid whenthe packages are made for Seidlitz powders which are usually wrappedinto conventional blue and white paper. In. the hopper H is arrangedabout midway of its height a rotary agitato la, the arms ofwhicli keepthe powder in motion, break up any lumps and prevent the clogging of thesame. The stirrer-shaft h1 receives an intermittent rotary motion bysuitable power-transmitting mechanism from the driving-shaft S of themachine. At the lower end of the hopper H yis ai'- ranged a box-shapeddelivery-portion H1 in which is arranged a second transverse shaft'lwhich is preferably made of square shape at the inside of the box-shapedportion H1 and which is provided on each of its sides with brushes71,3.' The brusli-shaft h2 receives like the stirrer-shaft h1intermittent rotary motion so that the brushes are moved over ahorizontal screen h4 which is supported on suitable cleats h5 at thebottom of the box-shaped portion H1 so as to feed a,

. delivery opening o in the bottom of the box.-

shaped portion H1. In the drawing, the drum D is arranged with sixopenings, but it is obvious that any other number of openings may bearranged in the same. The drum D is provided at each inlet-opening 01with a stationary compressing cylinder l in which is located a piston d1having a pis` toii-rod d2 which is guided in aii opening of the closedinner end of the cylinder d. Intermittent motion is imparted to thepistons d1 so as to produce first the compression of the measured offquantity of powder, next a forward motion for delivering the compressedcakes .onto a paper-wrapper, and then a return-motion for returning thepistons into their initial position for receiving the next quantity ofpowder through the feed-opening 0 in the lower box-shaped por-v tion ofthe hopper. The shape of the cylinder and pistons corresponds to theshape of the feed-openings o and o1; Each compressing cylinder (l isprovided sidewise of the piston-rod d2 with a stop-screw (Z3 by whichthe inward adjustment of the piston is regulated and the same held in aixed position when receiving the powder delivered to the cylinder. Thepositions of the stop-screws d1 are adjusted according to the quantityof powder which is to be delivered to the piston and the degree ofcompression to be imparted to the cakes. The quantity of powder to bedelivered to each compressing cylinder of the drum D is furthermoreregulated by raising the brush-shaft h1 into a somewhat higher or lowerposition in the box-shaped portion H1 by means of two exterior plateslz" located at opposite sides of the box-shaped portion H1, which platesare pivoted at one end of the side-wall of the vboxI-I1 and providedwith bearings for the ends of the shaft k2. The shaft 11.2 is guided inslots o2 of the side-walls of the box-sliaped portion H1. The oppositeend of each pivot-plate h6 is provided with an arcshaped recess ifthrough which is passed a clamping-screw las, as shown in Fig. 7, forpermitting the vertical adjustment of the plates h6 and shaft 11.2 andthereby the more eective feed-action of the brushes Ir* on the powder inthe box-sliaped portion H1 and the delivery of a smaller or largerquantity of powder through the feed-openings o into the cylinder d thenbelow the opening o. The adjusting plates are arranged at opposite sidesof the box-shaped portion H1 so as to set thereby the shaft of thevfeedbrushes at both 'ends slightly higher or lower relatively to thescreen h1. The feed-brushes k3 force the powder with a variable pressurethrough the meshes-of the screen k* and feed after proper adjustment auniform quantity of powder through the sani The exact quantity requiredis fed to each compressingcylinder of the drum D, after. brushes on theone hand and the pistons on the other hand are properly adjusted, sothat these measuring devices operate with an accuracy equal to weighingdevices. For some powders, especially for pulverized crystalline powder,such as tartaric acid, the screen can be dispensed with, as they are notliable to clog and move freely and easily under the pressure of thebrushes to and through the feed-opening, while for impal- .pablepowders, such as sodium bi-carbonate.

it is preferable to'use a screen and force the powder through the meshesof the same.

Intermittent rotary motion isimparted to the drum D and simultaneouslyto the shaft of the agitator and feed-brushes from the driving-shaft Sby means of a pinion p on the same, which pinion meshes with algearwheel 7) that is mounted on a short intermediate shaft S said shaftbeing supported in journal-bearings of the supporting-frame. A wrist-pinp1 on the gear-wheel p is connected by a pivot-rod Q53 with a crank-armp4 on a shaft S3 which is likewise supported in journal-bearings of thesupporting-frame of the machine. On the shaft S3 is mounted aratchet-wheel p5 which is provided with the feedas many teeth andrecesses as there are eompressing-cylinders in the drum, the recesses ofthe ratchet-wheel being engaged by 'a spring-actuated pawl p on theouter end of the crank-arm p4 and by a check-pawl p. A second crank-arm8 is mounted on the shaft S3 and connected y a pivot-rod p with acrank-arm p1" and by a pawl p at the end of the pivot-rod 9 with aratchet-wheel p13 keyed to the shaflt S4 of the drum D, so that by theintermediate pawl and ratchet-wheel mechanisms and crank. connections,an intermittent rotary motion equal to 1/6th of the circumference of thedrum is imparted to the same and thereby one compressing-cyl.- inderafter the other fed into register with the' feed-opening in the bottomof the boxshaped hopper-portion H1. On the intermediate shaft S3 ismounted sidewise of the ratchet-wheel p5 a gear-wheel p15 which mesheswith a pinion p on the short shaft p12 which is supported in bearings ofthe machine-frame. On the shaft p12 is keyed a sprocket-wheel p1 whichtransmits by a sprocket-chain p and wheel p18 intermittent rotary motionto the shaft h2. of the feed-brushes and by another sprocket-wheel andchain transmission p1 and p20 to the shaft h1 of the agitator h, asshown in Fig. 5. On the supporting-frame for the motiontransmittingmechanism is supported'an inclinedl block B, the concave face of whichis concentric with the drum D and forms contact with the circumference-face of the drum, as shown in Figs. 5 and 6, and closes therebythroughout the rotation of the drum the opening o1 of the same which isat the time in register with the face of the block B. This block Bserves to hold the charge of powder supplied to the openings o1 of thedrum and to the cylinders d, while the inner ends of the pistons receivean outward motion by an intermediate mechanism, which is shown clearlyin Fig. 5 and which consists of an oscillating lever b, which isfulcrumed to a fixed supporting arm b on the frame of the machine. Theupper end of thearm b acts on the piston-rods of the cylinders while itsouter slotted end is actuated by a connecting-rod b2, the upper end ofwhich is pivoted to a wrist-pin b3 on a crank-disk b* placed on theshaft p12 of the sprocket wheel p1". By adjusting the lower end of theconnecting-rod b2 nearer to or farther away Jfrom the'fulcrum of t-heoscillating bar b, the compression of the powder in the compressingcylinders of the drum D is regulated in proportion to' the greater orsmaller degree of compactness to which it is to be compressed. Thiscompression takes place when the drum D has completed onesixth part ofits rotation which commences with Ythe registering of the first cylinderwith the feed-opening of the hopper. When the drum is moved for 'thenext one-sixth of its rotation, the compressed cake of powder is held4Wit-hout any further action in its cylinder while at the end of thethird onethe base-plate of the sixth part of the rotation of thecylinder the cake arrives at a point diametrically opposite to thefeed-opening o and is delivered onto a wrapper placed below the drum onmachine, by the action of a curved pusher e, which forms the upper armof an elbow-lever e that is pivoted to a standard e2 attached to thebase-plate of the machine. The elbow-lever e is connected at its apex bya pivot-rod e3 with the wrist-pin b3 on the crank-disk b* so as to beoperated at the proper time whenever one ofthe compressing cylindersarrives at the end of the third one-sixth part of the rotation of thedrum. The pusher e acts on the piston-rod (l2 and pushes the pistou d1downward and delivers the cake from the cylinders to the wrapper. Duringthe next one-sixth part of the rotation ot the drum D, the pistonremains in its forward position in the cylinder, as sho-wn in Fig. 6,while after the fifth one-sixth part of the rotation of the drum D, thepiston d# is returned into its normal position at the inside ofthecylinder into contact with its stopscrew d3 by a pusher-lever f whichisl fulcrumed to an upright standard f on the base of thesupporting-frame, said pusherlever being provided with an a'rln f2 thatextends inwardly into the cylinder so as to contact with the Apiston ofthe same and return the piston into its initial position ready toreceive the next charge when the drum arrives at the end of the lastone-sixth part of itsfrotation in register with the feedopening of thebox-shaped portion H1. The lower end of the fulcrumed pusher-lever isconnected by a pivot-rod f3 with the wristpin b3 on the crank-disk b4 sothat the pusher-lever is actuated at each full rotation of thecrank-disk. During the next rotation of the drum the same steps, namely.feeding the powder, compressing it into a cake, delivering it onto awrapper, and returning the piston, are successively repeated for eachrotation of the drum and as many cakes of powder delivered as there arecompressing cylinders in the drum.

As some of the powder is carried along from the feed-opening o on theexterior surface of the drum D, as each cylinder passes beyond thefeed-opening of the box-shaped portion H1, a scraper g is arranged incontact with the surface of the cylinder D, the upper end of the scraperbeing'attached to the end-wall of the box-shaped portion H1. By means ofthe scraper, any adhering powder is removed from the surface of the drumand delivered over 1the side-edges of the drum to a' suitable receptaclewithout being lconducted int-o the/narrow space between the compressingcylinders (Z and the compressing block B so that not the slightestincrease in the quantity of powder in the compression-space between thecylinder and moved forward over its -block can take place. At one sideof the hopper H is arranged a spring-actuated knocker 7L", thespring-arm of which is actuated by the sprocket-wheel on the shaft 71,2.The blows of the knocker on the lower part of the hopper shake up thepowder and deliver it freely to the feed-brushes.

The measuring and compressing machine forms the subject-matter of aseparate application led by Isidor Z. Garfield on March 13,1912, ser.No. 683,522. Y It is obvious that any other measuring and compressingmechanism for delivering cakes of uniform weight and round or othershape may be employed.

The feeding and side-folding mechanism 0f the paperbamd-The paper issupplied wrappers required for the packages. The

^\ tent feed of the temporarily-compressed cakes are dropped at therequired equal distances fromeach other on the intermittently-movablepaperband so that a sufficient space is left between the cakes to bringthem into the center of the wrapper-blanks. The intermitpaper-band isimparted from the shaft S of the gear-wheel 7) to avv shaft S which isconnected by a universal joint y' with the shaft S and by anotheruniversal joint j with a horizontal shaftv S6 which turns in suitablebearings of a separate vsupporting-frame F for the left-hand end of themachine and which supplies the required power for the intermittentfeeding of the paper-band over Vthe supporting guide-plate F thatextends from the compressing drum to the frame F, also the lpowerforactuating the cutting oil", endfolding, delivering and countingmechanisms. The frame F is connected with the frame of the compressingmachine by longitudinal parallel bars F2. On the right-hand end of theshaft S is mounted a wormwheel fw which meshes with a second worm-.wheel rw of equal size, which is located at right langles to theworm-wheel fw below the same and the shaft 'w2 of which is supported inlbracket-bearings of the frame F for'` transmitting by acrank-rod m4connected with a wrist-pin w3 on the wormwheel 'w' oscillating motion tolever 105,' which is pivoted at its lower end to a crossbar F2 of theframeF andv which is pivotally connected at its upper end vwith areciprocating carriage we, guided on ways 107 ofthe frame F. In ears atthe upper frontend of the reciprocating carriage w-6 is supported alateral pivot-shaft w8 which expawl 102, that is pressed and 4respectively,

tends over the side-folded paper-band and which carries a downwardlyprojecting feedin downward direction during the forward motion of thecarriage by a spring-finger w1 which presses on the upper curved edge ofthe feed-pawl, as shown in Figs. land 8. The wormwheel transmission isso proportioned that for each rotation ofthe gear-wheel p and shaft S2,an oscillating forward and backward motion is imparted to the lever 'w5so that it moves at each forward motion by the engagement of the sharpedge of the Apawl w the paper-band forward immediately after a cake o fpowder has been delivered bythecompressing drum on the same. The bitingaction of the pawl and the forward feeding of the paper-band takes placeduring theoscillating motion of the lever lw5 toward the left, while bythe return-motion of the level-fw5 toward the right the feed-pawl ismoved freely in backward direction over the paper-band ready for thenext feed-motion of the pawl. A transverse bar fwn onfthe reciprocatingcarriage lw extends over the paper-band adjacent to the feed-pawl wg, asshown in Fig. 1, and holds thereby the paper-band in position for bveingfed'by th'elfeed-pawl over its supporting guide-plate F toward theend-,folding mechanism at the vleft-hand end of the machine.

By the forward movement of the paperband over its supporting guide-plateF, there is firstformed at one edge by an inclined folder z', -andcreaser which are arranged on the Aleft-hand side of the lguideplate Fnear the compressing drum, a narrow creased edge-strip Z, as shown inFig. 4. Thezfolder z' bends over the edge l and the creaser 2'. beingsmaller in size than the folder z', produces the. crease-line in thepaper-band. 'Simultaneously therewith the left-hand side of thepaper-band is folded over thecakes toward the right-hand side of the,same, as shown in Fig. 42. The creased edge-'strip `Z serves to contactwith the paper-band land serves to hold the foldportion in a lslightly-curved poSied-Over tion, inthe nature of'a loose bight so thatpressure on the cakes' is prevented and the same carried along with thepa er-band until the paper-band is doubleolded at its right-hand side.The double side-folding of the paper-band is accomplished gradually bythe successive action of the turnover folders, 2, i3, z", which arearranged on the right-hand side of .the guide-plate F, as shown inFig. 1. The folders 2, 712,'4

-fold the right-hand side of the paper-band' over the creased strip, asIshown at l and then fold it with thev creased strip into a double foldZ2; as shown in the Figs. 43,4",

so that when the paperband arrives 'near the feed-pawlit is closed bythe double fold. During the side folding of the paper-band, the foldedportion is held on the guide-plate by suitable cross-strips. After theside-'folded paper-band has'passed beyond the feed-pawl, it is cut offmldway between the cakes delivered thereto by a fulcrumed cutting deviceC which consists of a stationary knife 7c and an oscillating andvertically reciprocating knife k,'which latter is operated by means of adownwardlyextending cam 7a2 on the shaft S3, said cam engaging a pin 7c3at the lower end of a pivoted arm la* which is held 'by a spring lo incontact with the cam 7a2 while the cutting operation takes place. Theportion of the side-folded paper-band, which has been moved past thecutting-device into the endfoldingmechanism is thus cut of and forms thewrapper proper, which is then folded at the ends and moved forward fordelivery.

The end-folding mechanism.-The sidefolded wrapper containing the cake isnext taken up by the end-folding mechanism and moved through an angle of90 from its horizontal osition into a vertical `position by anV oscilating plate or platform a of the end-closing mechanism. The platform nis hinged at its inner end and connected at the underside of its forwardend with an actuating cnecting-rod n', the lower end of which isconnected by an anti-friction roller n2 with the cam-groove of a cam n3on the shaft SG. Each rotation of the shaft S6 imparts an up and downtilting motion to the platform n and moves thereby the wrapper intovertical position along stationary sidewalls n* by which thewrapper-ends are bent over at right angles to the body-portion of thewrapper Z3, as shown in dotted lines in Fig. 10a and in full lines inFig. 10b. During the upwardly-tilting motion of the wrapper, it ispassed along by a spring-finger a5. In this position the rectangularlybent-over ends of the wrapper are acted upon by laterally-oscillatinglingers a6 which fold the bent-up ends of the wrapper over on thebody-portion of the' same, as shown in Fig.

10c. The motion of the fingers a is accomplished by means of fulcrumedlevers a7 which are pivoted at their upper ends to the lower ends of thefingers 'n.6 and at their lower slotted ends to a pin on the cam-rod fn.of' the platform, so that during the upward motion of the cam-rod n thefingers are moved outwardly and during the downward motion of theplatform inwardly for folding the ends of the wrappers over thebody-portion of the same. lThe end-folded wrapper is next pushed forwardby the next following end-folded wrapper over curved guide-fingers ninto the ad]acent end 1"` of a delivery-channel r. The connecting-end rof the delivery channel 7' is curved in the form of a quadrant of acircle while the main-portion is straight and arranged parallel with andalongside of the supporting guide-plate for the paper-band, as shown inFig. 1. A second spring-actuated finger Va extends over the upper edgeof the raised. wrappers so as to hold them in proper position for beingpushed forward lnto the curved portion of the delivery-channel r. Theupper edges of the'wrappers are thenl passed under a stationary angularuide-arm 11.1 and then forward between e curved side-walls of'thedelivery-channel into the straight main-portion of the same.

Alongside of the curved end-portion 1" of the delivery-channel 'r isarranged an intermittently-rotated disk 'n.11 which is provided withpins no on its face that are engaged by a spring-pawl 11,12 which isoperated lby means of a spring-actuated connecting-rod n having ananti-friction roller n at its lower end. The roller 'n.14 engages a camn at the outermost end of the shaft S so. that the disk n is turned forone twelfth part of its rotation on every rotation of the shaft S6. Forthis purpose the disk nu is provided with twelve teeth or pins on itsface. Y 0n the circumference of the disk 'nu is arranged in radialalinement with one of the pins, a longer tooth n which engages thedownwardly-extending arm- 1t" of a rocking-lever a and produces thelifting of the longer arm of the rocln'ng-lever a that enters through aslot in the side-wall of the curved portion of the delivery-channel rAand the raisin of every twelfth wrapper into a diagonal y inclinedposition, as shown in Fig. 2, so as to separate thereby the wrappersinto dozens for the convenient packing into boxes for shipment. Thewrappers are pushed forward along the curved portion of the delivery-channel into the straight portion, while the inclined separating wrappersare guided along the upper edge of the outer side-wall of thedelivery-channel 1'.

In place of dividing the wrappers into groups of one dozen each, theymay be di-- vided into groups of ten wrappers, in which case, however,the actuating disk for the rocking-lever is to be provided with teninstead of twelve teeth.

By the pressure exerted on the package during the folding over of theends of the wrappers and by the forcible forward pushinv of the sameinto the delivery-channel a sultlicient pressure is exerted on thebodyportion of the wrappers for crushing the cakes in the same andchanging them back into powder-form so that flat wrappers of the usualshape are obtained. l

The delivery mechanism- The delivery mechanism consists of thedelivery-channel r, a plate r2v which is located in and guided,y

by the side-walls of the channel 1', and a. t.

delivery-tray ravwhich is placed in the channel .and pushed under theplate r2. To the delivery-plate r2 a horizontally-reciprocat- 'everyinclined twelfth package.

ing motion is imparted by means of a transverse rod T4 which is attachedto the upper slotted end of the oscillating lever wf and which serves toengage one or the other oi' two downwardly-extending pins T5 on theingoing end of the delivery-plate T2, as shown in Figs.v l and 2. Thepins T5 pass through slots T6 in the bottom of the delivery-channel T.The delivery-plate T2 is provided at opposite sides with fiat crimped-upinclined teeth T'r which during the left-hand motion of thedelivery-plate are moved un-4 der the'lower edges of the wrappers fed tothe same from the curved portion T of the delivery-channel and thencarried along by the motion of the delivery-plate T2 toward the rightover toward and on a delivery-tray T3 until the same is entirely filledup with Wrappers divided into groups of twelve by The fiat teeth of thedelivery-plate T2 gradually push the wrappers forward so that the samedo not exert any backward pressure on the wrappers in the curved portionT and the end-folding mechanism. When the delivery-tray T3 is graduallyfilled up with wrappers, it is removed and a'new tray placed in positionunder the reciprocating delivery- 'the combination, with a combinedmeasurf ing and compressing device for the powder, 'of means fordelivering the cakes formed plate to be lled again with wrappersdelivered by 'the delivery-plate. Simultaneously with the oscillatingmot-ion of the lever lw, a counter D is operated by an oscillatingconnecting-rod u which` is pivoted to -the reciprocation, rod T'i at oneend and connected with a crank u on the countershaft at its oppositeslotted end by a pin u2 so that the shaft of the counter is operatedwhenever the connecting-rod u arrives at the end of its motion.' Thecounter serves for counting the total nu ueber of wrappers made anddelivered by the machine within a given time.

The machine is mainly intended for packaging- Seidlitz-powders, but itis obvious that any other powders which 'are to be packed into wrap ersclosed-at the sides and ends,- can be pac ed by the same, without lossor waste, which is mainly due to the temporary compressionl ofthe powderinto cakes, which cakes are afterward, by the end-folding of thewrappers and the pressure exerted thereon, crushed and changed intopowder-form, the temporary compression of the powderA into cakes servingonly for the purpose of preventing loss of material and from thewrappers during the folding operations and during the transmission ofthe wrappers from the measuring and compressing mechanisms to theend-folding.
